Drawings form Plaistow Works.The majority of these drawings originate directly from the drawing offices of the Plaistow Works and later of the Derby Works of the Midland Railway. These represent only a small proportion of the drawings originally created by this institution. Other drawings in the collection were made for the use of the Plaistow Works by contractors who supplied locomotives, carriages and associated mechanical equipment. These contractors included Dubs & Co Ltd, Sharp Stewart & Co Ltd, Beyer Peacock Ltd, Westinghouse and other companies.
